The game Im trying to set it up for is a F2P game called Aika (click for downloadpage). The game does use X-Trap which I've heard may or may not be an issue. I'm hopeful as the game is made/published by the same company as Aion (gPotato).
Essentially all I did was clicked at the bottom to add game, chose Other, and pointed it to AIKALauncher.exe
Somewhere I set it up to do 2 characters or whatever and setup the display layout so both would show on 1 monitor
When I tried to run the game profile, the launcher popped up (only one did, not 2) I clicked start then it disappeared and nothing happened.
